I do not believe that this is set at the product level (PARMLIB), but is for the API(?) call.
My reasoning and sorry for the "Round About" way I am getting to it. Let's take an example of a TCP/IP commands that accept both a Host Name and a IP Address. I think this because NSLOOKUP which accepts either Host Name or IP Address without specifying anything to distinguish it, although you used to a LONG LONG time ago. NSLOOKUP is depreciated, so may go away at some point. NSLOOKUP's replacement is called DIG (dig under USS) When you invoke DIG, you have to tell it if you are sending a Host Name (no parm): dig www.ufl.edu Or if you are using an IP address: dig -x 128.227.9.98 If you did the above without the "-x" you will not get an answer.
